Title: Gas turbine engines including exhaust reheat combustion equipment
IPC: F02K1/82
Filed: 1974-01-31
Abstract: 1458054 Gas turbine jet propulsion engines GENERAL ELECTRIC CO 31 Jan 1974 [9 Feb 1973] 04483/74 Headings F1J and F1L The invention relates to an exhaust re-heat system of a gas turbine engine in which a liner is disposed within the engine jet pipe to define therebetween a plenum space to which cooling air is supplied and from which it discharges through openings in the liner into the re-heat combustion zone. The engine shown is a by-pass type engine, air from the fan or L.P. compressor 15 passing through by-pass duct 22 and mixing with gases discharging from the turbine 14 in a mixing device 32. The re-heat combustion zone 40 is disposed downstream of the mixer and is defined by a liner 46 located within the jet pipe 44 cooling air from the by-pass duct 22 passing into the plenum space 48 defined between the jet pipe and the liner. The cooling air passes through openings 54 formed in the liner into the re-heat combustion zone 40. The object of the invention is to make the pressure drop across the openings 54 move nearly uniform along the length of the liner, and this is achieved by dividing the plenum space 48 into a series of interconnected chambers 78, 80, 82 by means of a series of flanges 76 which provide openings 84 of reduced height into each chamber.. Each flange 76 is associated with a support device 56, each of which comprises a circumferential row of struts 58, a securing member 60 which is secured to the jet pipe 44 by means of bolts 70, a ring member 62 being interposed there-between. The forward edge of the ring member is extended as a radially inwardly directed flange 76 which defines the restricted inlet to a chamber such as 80.

Title: Work-clamp for sewing machines
IPC: D05B3/06
Filed: 1929-02-12
Abstract: 322,952. Fairweather, W., (Singer Manufacturing Co.). Feb. 12, 1929. Buttonhole sewing-machines.-The elements of a work-clamp in a button-hole sewing machine have closing means controlled by the thickness of the work. The invention is illustrated in a buttonhole sewing-machine of the kind described in 183,873. The work-clamps 8 are carried by arms 7 secured by screws 6 to blocks 5 pivoted between lugs 3 on the fulcrum block 2 of the plate work supporting plate 1, which carries the usual clamping members A, B, cross-slide plate e, and longitudinal slide frame f, g. The clamps 8 are depressed into holding engagement with the work by cams 12 carried by pins 9 interconnected by rods 10, 10<1>. The cams are operated manually by the lever 23, or mechanically by the lever 24 and connection 24'. The cams carry extensions 13 connected by springs 19 to the extensions 18 of wedges 15 sliding on the arms 7. As the pins 9 are rotated, the arms 13 advance the wedges along the arms 7 owing to the spring-connections, bringing them below the cams 12. When the clamps 8 contact with the work, the springs are no longer effective to advance the wedges, which are pressed down by the cams 12, together with the arms 7 and clamps 8 to hold the work. The device therefore accommodates the clamping pressure of each element to suit the thickness of the work, and the clamps, when released, rise to a constant height under the action of the springs.

Title: Improvements in or relating to control mechanism for hydraulic presses and like machines
IPC: B30B15/16
Filed: 1938-02-17
Abstract: 495,536. Hydraulic presses ; hydraulic transmission of power ; liquid - pressure engines. LAPOINTE MACHINE TOOL CO., Ltd. (Lapointe Machine Tool Co.) Feb. 17, 1938, No. 5023. [Class 69 (ii)] A tube-drawing press or like machine comprises an hydraulic actuating mechanism 18, a distributing valve V, automatically operated spring means 65 for alternately reversing the valve and manually operated means 82 controlling the reversing means and normally preventing movement thereof beyond the neutral position in one direction only, whereby the piston 17 always stops in the retracted position relatively to the work. A distributing valve V for the cylinder 18 is connected by links to one arm of a bell-crank lever 56 the other arm of which is connected to a hand lever 52, having a pin 93 pressed by a spring 65, when the press is inoperative, in the bottom of a slot 92 of a lever 90 carried by a pedal 82. Depression of the pedal releases the lever 56 which is then rotated by the spring 65 and operates the distributing valve to effect a downstroke. The valve is reversed automatically at each end of the stroke by tappet means 75, 76, 77 so long as the pedal remains depressed. On release of the pedal a spring 86 raises the lever 90 and limits downward movement of the lever 52 thereby bringing the distributing valve to neutral position with the piston 17 at the top of its stroke. A lost motion connection between levers 57, 58 in the valve operating mechanism ensures that the spring toggle 65, 56 passes its dead centre position before the valve cuts off oil supply to the cylinder. The hand lever 52 may be operated to effect any desired movement of the press independently of the pedal.

Title: Metal film resistor
IPC: H01C17/06
Filed: 1948-02-20
Abstract: 640,323. Resistance coatings and deposits; couplings. CONTINENTAL CARBON, Inc. Feb. 20, 1948, No. 5121. Convention date, Feb. 3, 1940. [Classes 37 and 38 (i)] [Also is Group II] A process of constructing a metal film resistor includes the steps (1) coating a non-conductive carrier with a metallo-organic compound comprising an organic resinate of a substantially stable and non-oxidizable metal, for example palladium or platinum resinate; (2) heating the coated carrier to a temperature below the melting point of the resinate to atomically deposit a thin continuous metal film on the carrier; and (3) heating to oxidize the carbonaceous residue remaining after the deposition of the thin film of metal. A ceramic tube 10, Fig. 3, is coated with palladium-resinate 20. The latter may be applied with a suitable solvent such as ketone to reduce the concentration of palladium. The coated tube is dried in air at 20‹ to 25‹ C. and then heated in a temperature ranging from 200‹ to 400‹ C. This treatment effects precipitation of pure palladium accompanied by a residue of carbonaceous ash mixed with the pure palladium as represented at 21, Fig. 4. A second heating of the carrier in a temperature ranging from 400‹ to 750‹ C. oxidizes this residue leaving a thin palladium film 11 firmly bonded to the carrier 10, Fig. 5. Further coatings may be added at different stages. The ohmic value may be varied by grinding a helical groove in the carrier. To furnish the resistor with terminals, Fig. 1, a coating of metal 12, for example colloidal silver fired on at 500‹ to 600‹ C., is formed about the ends of the palladium film 11 and copper bands 13 are then clamped in contact with the silver coating 12.

Title: Improvements in or relating to air intakes for jet-propulsion power plants
Inventor: BRITT JACK
IPC: F02C7/042
Filed: 1953-02-24
Abstract: 761,235. Gas turbine jet propulsion plant. ROLLS-ROYCE, Ltd. Feb. 16, 1954 [Feb. 24, 1953], No. 5197/53. Class 110 (3). An annular air intake for a jet propulsion engine comprises an annular shell the forward part of which is movable axially from the main part to form an annular gap at subsonic velocities below a selected value and a centre body with a pointed forward end which projects forwardly of the plane of the inlet to the annular shell at supersonic velocities above a selected value. The air intake shown comprises a circular annular outer shell 10 and a centrebody of circular cross-section. The outer shell has a sharp edge 10a at its forward end and its inner and outer surfaces 10b, 10c diverge at a small angle, say 3 degrees. The inner surface 10b is also slightly divergent with respect to the axial direction at a small angle, say 3 degrees, and is so shaped with respect to the centre-body that the area of the intake passage 12 increases for a considerable distance in the direction of air flow. The centre body has a sharp point 11b at its forward end. The sections 11c, 11d are so shaped that at supersonic speeds a series of relatively gentle shockwaves are formed at different points on the surface of the body 11, which shock-waves intersect on a circle lying in a plane at rightangles to the axis of the intake of greater radius than that of the annular outer wall. The section 11d is connected to the cylindrical surface 11f slidably mounted in a tube 13a forming part of a fixed fairing 13. The centre-body 11 is movable from the position shown to the position shown in chain lines by a piston 15 acting through a rod 15a. The forward end part 10f of the outer shell is movable axially forwards with respect to the main part 10e by means of rams 17. At a forward speed corresponding to a Mach No. of 1.0 the parts are in the position shown in which the point 11b is in the plane of the forward edge 10a. As the Mach No. is increased the angle between the shock-waves and the axial direction decreases. To ensure that the shock-waves are also intercepted by the shell 10, the centre body 11 is moved forwards at the Mach No. is increased. This movemens may be effected automatically by using the pressure rise which occurs across the shock waves when they are intercepted by the outer shell 10. Below a Mach No. of 1.0, the centre body 11 is held in the rearmost position and the forward end part 10f moved forwards to allow air to enter the gap between 10e, 10f. The movement of 10f may be a progressive one or effected at a particular Mach No. In a modification, the centre body is fixed but its apex is arranged forwardly of the plane of the edge 10a when the part 10f is fully retracted. The amount by which the apex protrudes is determined by the Mach No. for which the intake is designed. The arrangement is such that at this Mach No. the shock waves are just intercepted by the forward edge 10a. Specification 717,760 is referred to.
